Abstract
The use of antibiotics at a sub-therapeutic level as growth promoters raises concern worldwide because of the possible tolerance that some microorganisms can develop against some antibiotics which could, in a potential manner transfer resistance genes from animals to human microbiota. There are some alternatives such as probiotics and prebiotics that stimulate the host’s immunity and do not leave any residue in any animal origin products; therefore, this research intends to study its effects on the pigs’ diet and to identify the main deficiencies visible in the experimentation carried out with them. Probiotics are live microorganisms that, when administered in the right amount, create benefic effects in the host, lowering health problems, and raising productivity because they can affect the proportions of different species of bacteria in the in the gastrointestinal tract microbiota; however, as far as its effect as growth promoters, the results are contradictory mainly because of the wide diversity of strains and species doses and administration forms as well as different composition of the diets used in the bioassays.
